BIODEGRADATION OF TERT-BUTYL ALCOHOL (TBA) USING BIOLOGICAL GRANULAR ACTIVATED CARBON (BIO-GAC) BY KAYLEIGH ANNE DUNNETT THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Environmental Engineering in Civil Engineering

Ammonium removal in granular activated carbon up-flow submerged reactors containing native bacterial consortium

Free ammonium in industries wastewater could be one of the worst toxic contaminants of aquatic life if diluted in water. Biological nitrogen removal (BNR) is the most common method for removing ammonium and nitrate from wastewater. Attached growth and suspended growth are the main BNR systems. The aim of the present work was to study the treatment of petrochemical wastewater (ammonium and nitra...

INCREASING FERMENTATIVE BUTANOL PRODUCTION IN CLOSTRIDIUM BEIJERINCKII USING OXIDIZED EXTRACELLULAR ELECTRON SHUTTLING MOLECULES BY ANNE HALUSKA THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Environmental Engineering in Civil Engineering

Nitrate Removal from Aqueous Solutions Using Granular Activated Carbon Modified with Iron Nanoparticles (RESEARCH NOTE)

Nitrate contamination of water resources and the growing concentration of nitrate endanger human health and the environment and considering its reduction strategies from water resources is important. The aim of this study was to investigate the possibility of removal of nitrate from aqueous solutions using granular activated carbon from grape wood coated with iron nanoparticles. The results sho...

Experimental Study and Adsorption Modeling of COD Reduction by Activated Carbon for Wastewater Treatment of Oil Refinery

Application of Granular Activated Carbon (GAC) in adsorption process has been studied for the advanced treatment of municipal and industrial wastewater. Because of entering poisonous compounds such as furfural, phenol and sulfides into the oily wastewater of Tehran refinery, biological aeration basins of wastewater treatment unit may not have the desired performance of COD reductio...

Rapid Biodegradation of Methyl tert-Butyl Ether (MTBE) by Pure Bacterial Cultures

Two pure bacterial strains capable of rapid degrading methyl tert–butyl ether (MTBE) were isolated from an industrial wastewater treatment plant, identified and characterized. These strains are able to grow on MTBE as the sole carbon and energy sources and completely mineralize it to the biomass and carbon dioxide. The strains were identified as Bacillus cereus and Klebsiella terrigena. Bot...
